Siemens Gamesa Renewable Energy (SGRE) has conditionally received a record order for 1,714 MW from Ørsted and Eversource. Encompassing three offshore wind power projects, the signed conditional contract is the largest US offshore wind power order to date. It encompasses the supply, delivery, and installation of SG 8.0-167 DD wind turbines including service agreements in federal waters off the northeastern coast of the US. All deliveries are subject to Ørsted and Eversource’s final investment decision.

Siemens Gamesa has been conditionally awarded the contract to deliver offshore wind turbines totalling 880 MW for the Sunrise Wind project, which will be the company’s largest offshore wind project in the US. Ørsted and Eversource were awarded this capacity by New York State. SG 8.0-167 DD offshore wind turbines will be utilised at the project in federal waters about 50 kilometres off Montauk Point in New York. A service agreement is included. The Sunrise Wind project is expected to be operational in 2024.

The 704 MW Revolution Wind offshore project will be located 24 km off the coast of Rhode Island. The project will utilise SG 8.0-167 DD wind turbines and is expected to be online by 2023. Once operational, Revolution Wind will deliver power to Rhode Island and Connecticut.

Additionally, SGRE was conditionally awarded the contract to deliver SG 8.0-167 DD offshore wind turbines for the 130 MW South Fork offshore wind power project. Located 56 km off Long Island, NY, it is expected to be operational by the end of 2022 and will deliver power to the Long Island Power Authority.

“An order of this size is a testament to the confidence which Ørsted and Eversource place in Siemens Gamesa. Delivering clean energy for generations to come – now on a large-scale basis in the US offshore market – is a goal we are proud to share with Ørsted and Eversource. We are committed to doing so safely and with a strong focus on reducing the Levelised Cost of Energy from offshore wind in this rapidly developing market,” says Andreas Nauen, CEO of the Siemens Gamesa Offshore Business Unit.

“We had already secured a US construction pipeline of almost one gigawatt before the end of 2018 and have been looking into further growth in the US offshore wind market. We saw an opportunity to secure a bigger turbine volume early in order to gain economies of scale, and Siemens Gamesa was able to provide an attractive offering for this large volume,” says Anders Lindberg, Executive Vice President, EPC, at Ørsted.

“Siemens Gamesa has long been the global market leader in offshore wind with 12.5 GW installed. This major order signals that we are well positioned to maintain this leadership role in the budding US market,” says Steve Dayney, Head of Offshore North America at Siemens Gamesa Renewable Energy. “We have always believed in the potential of this market, and with the partnership of Orsted and Eversource, we are excited to bring 1.7 GW of clean, reliable offshore wind electricity to American communities in the northeast.”

The SG 8.0-167 DD wind turbine has a rated capacity of 8.0 megawatts (MW), and a rotor with a 167-metre diameter. It has a swept area of 21,900 m2, and uses the SGRE B81 blades, each measuring 81.4 metres. By 2020, more than 1,000 SGRE Direct Drive offshore wind turbines will be installed globally.

The US variant of the SG 8.0-167 DD is designed for IEC class S, considering tropical storm conditions (T-Class for the Rotor Nacelle Assembly). The T-class type certification for the Rotor Nacelle Assembly will be achieved by December 2020, where the product will be certified to handle extreme wind speeds in hurricane conditions in accordance with IEC 61400-1 edition 4. Furthermore, electrical systems and components will be adapted to 60 Hz operation.
